JD 1 Drive: "The Jadis system offers a unique sound aesthetic, placing the listener in the concert hall with a sound environment of unequaled coherence." - Patrick Vercher et Jacques Vallienne
With its refined and imposing looks, the JD-1 combines an extremely precise mechanism fully protected by a heavy rigid base mounted on four massive gold-plated steel supporting feet, with a highly futuristic appearence.
Our objective above all was to protect the laser disk from internal and external vibrations. The enormous inertia of the JD-1 was obtained by assembling opposing ground elements.
The CD turntable is divided into three sections by bronze rods placed uder the points of the three main supporting feet - the height of the foot at the back is adjustable. The upper deck, itself suspended in three parts, makes up a block of 8 kgs. The supporting rods for the suspension springs in the star-shaped upper deck enclosing the drive coincide with the two front supporting feet. The third spring point is at the centre back, coinciding with a supporting foot in chrome steel.
The original Philips CDM 4 mechanism was designed to read CD-Roms.
The laser diode block is mounted at the end of a galvanometric arm controlled by a digital servocontrol system.
The command panel , conveniently inclined for easy access to the function buttons, forms an entity with the base of the drive unit.
By using a very light disk clamp (in metacrylate), the performance of the motor bearing lasts for a much longer time than in the majority of other drives presently on the market. Furthermore, the JD-1 becomes a perfect darkroom once the sliding cover has been closed.
